在PHP中读取SOAP XML

如果使用php的内置库，它会解析响应并返回一个比xml 更容易处理的混合对象/数组对象

编辑：由于您使用的是php的内置客户端，这里有一个我围绕它编写的简单类。它"平坦"了响应，并使检索响应变得容易，如：

$soap = new SOAP($wsdl, $options);
$soap->call("stuff goes here");
$soap->find("what you are looking for goes here");
    /**

class Soap {
    //***VARIABLES***//
var $request; //..............string; holds last soap request
var $requestHeaders; //.......string; holds the headers for the last request
var $response; //.............string; xml response
var $responseHeaders; //......string; holds the headers for the last response
var $result; //...............array; the soap response parsed into an array
var $wsdlLocation; //.........string; url for the wsdl
var $parameters; //...........array; saved array of parameters
var $function; //.............string; name of function to be accessed
var $findResult = array();
var $flatArray = array(); //..array; holds an easy to search array
//
//***OBJECTS***//
var $client; //...................instance of SoapClient
var $exception; //................obj; SoapFault exception object
//    
//***DEFAULTS***//
public $options = array(
    'trace' => 1
);
function __construct($wsdl, $options = false) {
    if ($options == false) {
        $options = $this->options;
    } else {
